ATMOSPHERIC ENGINE.

Specification of Letters Patent.

Patented June 4, 1912.

To all whom it may concern Be it known that we, ALBERT R. WEIsz and GEORGE R. WEIsz, citizens of the United States, and residents of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have 1nvented certain new and useful Improvements-in Atmospheric Engines, of which the following is a specification.

This invention relates toimprovements in atmospheric engines and the object of this invention is to provide a new and improved motor of this kind which is simple in. construction, strong and durable, and effective and economical in use.

In the accompanying drawing a vertical diagram section of ournew and improved motor is shown.

The cylinder of the en-gine'is composed of two sections namely the upper section 1 and the lower section 2, the upper section 1 being of greater diameter. A piston 3 works in the upper section 1 and is of such diameter that there is a clearance between the inner packed at the lower end of said section 2 by suitable annular packing 5. The upperand larger cylinder section is provided with an inlet port 7 for the hot gases at the top and an outlet port 8 for the cooled gases at or near the bottom. An inlet valve 9 is suitably mounted to alternately open and close the inlet port 7 and a valve'10 is mounted to open and close the outlet port 8. These two valves are attached to a common rod 12, the lower end of which is provided with a pin 13 entering the cam groove 14 in the side of the cam disk lo'seoured on the main crank shaft 16 mounted in suitable bearings 17. The crank of the shaft is connected by a suitable connecting rod 18 with the underside of the piston The parts'are so dimensioned that when the piston 3 is in its lowest position it does not rest on the annular bottom part of the upper larger cylinder section, but is a short distance from the same, as indicated The outlet valve 10 is not rigidly connected with the valve operating rod 12 but pressure exerted on this valve it may yield outwardly.

On the top head-22 of the cylinder, we

provide a spring pressed puppet-valve 23- which can yield outwardwhen there is internal pressure in the upper end of the cylinder. The combined cylinders are supported by standards 24 from the base 26 in any suitable manner so as to form a rigid structure.

27 is a fly-wheel.

The cylinder is to be cooled by water jacket or fins or any other suitable cooling means.

When the piston 3 is at thetop of the cylinder the inlet port 7 and outlet port 8 are both open and hot gases can pass from a hot gas chamber 28 through the port 7 into the upper part of the cylinder, which hot gases are generated by asuitable burner or furnace 29 of any suitable construction, the

details of which form no part of the present invention and this burner or furnace may .be provided with solid, aseous or liquid fuel. When the piston has descended to about half the'height of the cylinder section 1 as indicated by the line 32 both valves 9 and 10 are moved so as to close-the inlet port 7 and outlet port 8 and the supply of hot gases is thus cutoff at the time when the crank has moved, say through an arc of 90 degrees, more or less. During the time that the piston 3 moves from the top of the cylinder to the line 32, the port 8 is open and the condensed gases beneath the piston 3 are partly forced out through the outlet port 8 until the piston position on line 32 has been reached. Then the ports 7 and 8 are closed and the piston continues to descend, the hot gases that have been admitted into the upper part of the cylinder section 1 coming in contactwith the cooler walls of the cylinder section 1, and the plunger or trunk, are cooled more orless, and as the the annular clearance between the rim of the.

piston and'the inner diameter of the cy1indcr and are further cooled by the resultant agitation thereof, and as these gases mix with the heated'and expanded gasesabove the piston .the temperature of the gases above the piston is still further reduced and this takes place until the crank has turned through an arc, s'ay fro1n'90 to'18O degrees when the piston, will be-in itsdowest posi-' .tion, that isv when the crank pin is on its hen the piston is in its lowestposition it does not come in contact with the shoulder 31 at the bottom of the larger section 1 of the cylinder but remains a short distance'above the same thus leaving an annular space 19 which is bounded by outer dead center.

the shoulder 31 at the bottom, the-underside of the rim part of the piston 3at the top,

the cylinder wall'at the outside and the cylindrlcal trunk wall 4 at, the inside. The fly-wheel now carries the crank pin over the 'outerdead center and the piston now makes the upstroke,.under the pressure of atmospheric air, the valves 9 and 10 being closed,

- and the condensed gases free to pass from above the piston into the space, forming beneath the piston. \Vhen the piston and trunk rise the gases which are forced through the annular space between the rim of the piston andthe inner'surface of the der, and this lower upper cylinder section come in contact with the walls of that portion of the trunk extending into the upper section of the cylinder, and thus are cooled. This trunk at all times had more or less of its surface sura cooled air, bounded by the or less diameter of the cylinportion being cooled and not coming in contact with hot gases serves to cool the air surrounding the trunk, and thereby to cool thetrunk. The valves 9 and rounded b lower portion,

' 10 remain closed until the piston has sub ycooling or water cooling,

A claim as new'and desire to secure by Letters stantially completed its up-strokc whereupon the valves 9 and 10 are suddenly opened and the cycle above described repeats itself,jand the gases thathave passed from above the piston. to beneath the piston are forced out by the pistonthrough the port 8 in its downstroke.

As explained, the valve 23 in the head of the cylinder may be forced u by any outward pressure developing int 1e upper part of the cylinder, thereby preventing undue resistance to the piston durin As shown either fins as in water jackets asindicated by b may be used for cooling the cylinder walls, either by air this depending upon the size of the-motor and upon the conditions under which and where it is used.

Having described our invention what we Patent is 1. In anengine. the combination with a cylinder composes of two sectlons,
